Methods (to address phases 3 and 4):

Planning Committee of key informants - gave insight into the characteristics of small woodshop owners and barriers to dust control

Focus groups - validated planning committee knowledge

Pilot test of outcome measures - provided info on the variety of controls to lower dust levels and range of exposure

Results: An intervention was designed using data from the planning committee, focus groups, and pilot test.

48 shops (24 control/24 intervention)

Random selection of 10 workers sampled for dust exposure

Control group received a letter in the mail with sampling results and recommendations to lower dust levels
